Big waves will stick around Monday, which may be troublesome for lifeguards watching over inexperienced spring break vacationers.
A High Surf Advisory was issued for San Diego County through Monday evening, according to the National Weather Service.
Waves could reach a high of 13 feet, with potentially hazardous rip currents that causes flooding. Waves on Monday will be bigger in the morning and then should simmer down by the afternoon.
Inexperienced swimmers and surfers should be on the lookout for dangerous conditions, and are encouraged to stay out of the water.
NWS also stated that the entrance to harbors will be particularly dangerous because of breaking waves and above average surf will continue into Tuesday. The entrance for Mission Bay was closed momentarily, but has been reopened.
